The event, hosted by the Westchester/Hudson Valley Chapter of The Leukemia & Lymphoma Society, raises funds to support blood cancer research and provide services to patients and their families. Each Light the Night Walk honors local blood cancer survivors and commemorates individuals who have lost their lives to these diseases.

Bickerstaff was diagnosed with acute myeloid leukemia when she was 45 years old. After a bone marrow transplant in 2009, she relapsed a year and a half later and has been on preventative chemotherapy treatment for the last 24 months. Bickerstaff says she is back to leading a relatively normal life and credits her will to survive to her two sons, James and Nicholas.

Bickerstaff first became involved with Light the Night in 2012 by participating in the Orange County Walk in Goshen. Her team, Sandra's Goal, was the top fundraising team for that Walk.

Last year, Light the Night Westchester/Hudson Valley Walks in Orange, Rockland and Westchester counties included more than 7,000 walkers who collectively raised $857,000.
